Yes, it does.  It is its purpose: to use the buildfarm to
first validate a commit before pushing it into main stream
branches.

That's a development model I have used elsewhere with great
benefits for everyone, since the main branches are much
less often broken for portability issues, or other reasons
that one would not find on her sole computer.

I see.  I don't want to be a problem and ask everyone for
more free efforts, but really, I'd like to emphasize
how beneficial for every project it would be for hydra
to change this command.  Then, every single project can exploit
the buildfarm to validate commits before carving them into
main branches.  There would not need to deploy several
means to update a checkout, as this approach is valid for
both monotonic, and non monotonic branches.

The sequence should be as follows in my humble opinion.

# Remove all the local tags.  That's the safest means
# to remove local copies of tags that have been removed.
# Existing tags will be re-imported by fetch.
# This matters for projects that use for instance
# "git describe" to forge version information.
git tag -l | xargs git tag -d 
git fetch
git checkout -f <branch-name>
git submodule update --init --recursive


Anyway, thanks!
